摘要
介绍数控车削加工工艺方案的拟定原则及注意事项,根据数控加工程序编制时的关键和难点,提出合理选择工件坐标系以保证加工尺寸、方便计算运动轨迹和加工过程的安全性;合理选择加工路线以减少空行程、提高生产效率;利用循环等数控指令提高编程的速度和质量;并用对比的方法指出不同数控系统的数控车床在应用同一数控指令时应注意的事项,为学习和掌握数控编程提供有效的方法与技巧。
The working out principle of NC turning processing plan and matters needing attention are introduced.According to programming key and difficult point,puts forward reasonable coordinate system selection to ensure machining size,convenient calculation of tool movement trace and machining safety,reasonable selection of machining route to reduce idle stroke and to enhance productivity,applying circular command to heighten programming speed and quality,by contrast to point out the matters needing attention when turning in the lathes with different NC system,but the. same command, which provide the effective ways and technique for learning and mastering of NC programming.
